and useful Improvements in Typographical Machines, of which the following 183 specification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to

O. Mergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through a distributing mechanism to the magazine from which they started.

More particularly, it relates to the devices whereby the matrices are transferred to the assembler in the course of composition.

In lino-type machines of this kind, the matrices when released from the magazine are delivered to a moving endless belt, from which they pass in front of a rotating star wheel by which they are advanced and compacted in the assembler; and at the side of the star wheel is arranged a cover-plate which serves to guide the edges of the matrices and insure their correct delivery. It occasionally occurs that matrices become clogged in proximity to the star wheel and behind the cover, which necessitates the displacement of the latter in order to permit the operator to clear the parts. To facilitate this operation, it is also desirable to arrest the rotation of the star wheel, and this has ordinarily been accomplished by its manual disconnection from the actuating devices.

It is a specific purpose of my improvement to provide means whereby the movement of the cover itself from and to oplerative position disconnects and connects t e star wheel and its operating mechanism, and as this same mechanism is employed for the purpose of'actuating the assembler belt, it follows that the latter also is simultaneously arrested and restarted.

In the accompanying drawings, I have shown my invention in preferred form and by way of example, and as applied to a linotype machine, but many changes and variations may be made therein, and in its mode of application, which will still be comprised within itsspirit. Thus for instance, it may be adapted to other forms of typographical machines, such as typesetters, typecasters, and the like, or that is to say, machines which handle type or, dies instead of matrices. Or again, the same principle may be applied in other'forms, so as to eifect the arrest of moving assembling devices, such as the star wheel or assembler belt, by suitable connections, when any adjustable part is moved from its operative position. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

In the accompanying drawings: Figure 1 is a front view, partly broken away, of a portion of a linotype machine, having my invention applied thereto; Fig. 2 is a detached view, on an enlarged scale and partly broken away, of my specific improvements; Fig. 3 is a sectional View on the line 3-3 of Fig.2; and Fig. at is a sectional view on the linett of Fig. 3.

The matrices are released from the magazine A by the manipulation of the keys A and are delivered to the assembler belt B, and by it' in turn in front of the rotating star wheel C, by which they are advanced and compacted in the assembler D, in conjunction with the spacers which are released fromthe magazine E by the manipulation of the space key E, all in the usual manner and as illustrated in the previouslymentioned Mergenthaler patent. The actuating means for the belt B and star wheel C comprise the rotating shaft G and connections therefrom to the countershaft J, which carries one of the pulleys B'of the belt B, and also the pinion K which connects through the chain of gearing K, K with the star wheel 0.

As previously set forth, a cover or plate F is located at the side of the star wheel G to guide the matrices as they pass from the belt B and to prevent their accidental displacement. It sometimes occurs that the matrices clog or pile up behind the plate F, and the latter is therefore mo-vabl-y mounted, as upon the rock shaft L, to permit its displacement from operative position and to give the operator access to the parts. In such circumstances, it is also desirable to arrest the rotation of the star wheel. This has ordinarily been accomplished by a distinct manual operation, and it is a principal purpose of my invent-ion to effect it automatically by connections from the cover F, in such manner that when the latter is moved from or to operative position, the actuating engagement is correspondingly broken or restored.

By way of illustration, I have shown frictional connecting means between the shaft G and the countershaft J ,these means comprising a disk J on the countershaft J, so located and arranged that it engages at its periphery with the side of a disk H, splined upon the shaft Gr and pressed normally into operative position by a spring H mounted within its hub and bearing against a collar H upon the shaft. The rock shaft L, whereon the cover F is mounted, is provided with an arm L, which is connected by a link L to one end of the shift lever M, pivoted at M and forked at its farther end M and engaging the groove H in the hub of the disk H,

' clogged matrices or the like, as shown in Fig. 2, the consequent rocking movement of the shaft L, through the arm L, the link L and lever M, shifts the disk H rearwardly against the force of the spring H, and thus breaks the actuating connection between the shafts G and J, which results in the arrest of the star wheel C and assembler belt B. When the cover F is returned to operative position, this actuating connection is restored.

As previously stated, I have shown my invention only in preferred form and by way of example, and in a special mode of adaptation, but obviously many modifications and alterations therein will suggest themselves to those skilled in the art, without departure from its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

1. In a typographical machine, the combination of the rotating star wheel G, the cover-plate F movable to and from operative position, and means whereby the movement of the cover-plate to inoperative posi tion arrests the star wheel.

2. In a typo-graphical machine, the combination of the star, wheel 0, actuating means therefor, the cover-plate F movable to and from operative position, and means whereby the movement of the cover-plate to and from operative position connects and disconnects the star wheel and its actuating means. i

In a typographical machine, the combination of the assembler belt B, the star wheel C, common actuating means therefor, the cover-plate F movable to and from operative position, and means whereby the movement of the cover-plate to operative and inoperative position connectsand disconnects the assembler belt and star wheel with and from the common actuating means.
